| Abstract: | The sol-gel procession of titanium alkoxide was studied through DTA-TG,XRD analysis methods.The study covers the influence of water volume,nitric acid and silver nitrate addition on the gelation time,thermal effects,weight change of sample and anatase-rutile phase transformation temperature.This article also discussed the mechanism of the observed variation of the phase transformation temperature,affected by all above parameters. |
